A new type of quantum holography which uses entangled photons to overcome the limitations of conventional holographic approaches could lead to improved medical imaging and speed the advance of quantum information science.

 A team of physicists from the University of Glasgow is the first in the world to find a way to use quantum-entangled photons to encode information in a hologram. The process behind their breakthrough is outlined in a paper published today (Thursday 4 February) in the journal Nature Physics.

Holography is familiar to many from its use as security images printed on credit cards and passports, but it has many other practical applications, including data storage, medical imaging and defence.
